A pair of simple cushion covers have been given such a beautiful makeover just by doodling pretty little butterflies fluttering around using Fevicryl 3D Neon Liners. There are bright orange, green, pink and yellow. All exciting and happy colours I would say. You could border your curtains in the same manner with a suitable pattern that you have in mind.
